The document discusses emerging technology that could allow people to edit and improve human memory. It notes that stored memories exist as physical changes in the brain, and new research may enable editing memories at will. One idea discussed is being able to scroll through memories like photos and perfectly recall everything ever learned. However, the document questions whether such technology would undermine what makes us human. It also outlines plans for a hypothetical service called "Memoral" that would allow viewing old memories on demand, including scents and sounds, and accessing all memories as long-term recollections.
